(2) The fermentation medium is directly used for culturing the compound microbial preparation without being disinfected in the finished product fermentation process, and is also not required to be stirred in the culture process, so that manpower and material resources can be saved, and the economic benefit is improved.
(3) The active ingredients of the microbial preparation for regulating the live pig intestinal flora mainly comprise live bacteria, dead bacteria and metabolites, and the microbial preparation is mainly used for changing the composition of the intestinal microbiota, enabling beneficial or harmless microorganisms to occupy population advantages, and regulating the live pig intestinal microbial ecological balance by competitively inhibiting the proliferation of pathogenic bacteria or harmful microorganisms. After the beneficial microorganisms enter the live pig intestinal tract, the beneficial microorganisms can rapidly form dominant microbial flora together with beneficial bacteria in the intestinal tract to inhibit the growth of harmful bacteria in the intestinal tract, wherein the beneficial microorganisms are tightly combined with intestinal mucosa epithelial cells through teichoic acid around the intestinal tract wall to form a bacterial membrane barrier, prevent the colonization of harmful bacteria and regulate the microecological balance of the live pig intestinal tract.
(4) The invention utilizes the prepared microbial preparation for regulating the intestinal flora of the live pigs to ferment the feed raw materials, and the growth and metabolism of the saccharomycetes are taken as the main raw materials in the initial fermentation stage, and the saccharomycetes can quickly consume O2And can endure strong acidic environment (about pH 3.2). When the yeast is consumed O2Later, favorable conditions are created for the growth and the propagation of bacillus, lactic acid bacteria and animal bifidobacteria. With the growth and metabolism of the lactic acid bacteria, the number of the lactic acid bacteria is continuously increased, some macromolecular nutrient substances (such as protein, polysaccharide, fat and the like) are continuously converted into micromolecular nutrient substances, organic acid, polypeptide, free amino acid, vitamin and the like are continuously increased, and the nutritive value of the feed is greatly improved. During fermentation, lactobacillus and bifidobacterium can produce organic acid such as lactic acid, acetic acid and the like, the pH value is reduced, the proliferation of escherichia coli, salmonella and the like is inhibited, the bacillus produces antibacterial peptide, and the lactobacillus produces bacteriocin, which can effectively kill harmful bacteria (such as escherichia coli and salmonella) in feed raw materials. The fermentation is close to the mature period, the lactic acid bacteria are absolutely dominant, the quantity of animal bifidobacterium strains, yeasts and bacilli tends to be stable, and a complex and stable microecosystem with multiple functions is formed. The production of the fermented feed can be completed only by three processes of inoculation, mixing and fermentation. The raw materials can be directly used for fermentation production without being sterilized, manual turning is not needed in the production process, the fermentation finished product does not need to be dried, a large amount of labor force can be saved, and the labor intensity of workers is reduced.
